C5 six-speed worst shifting manual ever?

Shifters
If I had just driven one C5 manual I would assume I had gotten a car with a defective transmission. But I have driven several, and they all shift like trying to stir a barrel of nails with a broom handle. Hard, balky, notchy, too-thin separation of gates, you name a negative quality for gearshifting and the C5 has it. Yeah, yeah, I hear you smarty-pants saying "get an automatic" or "if you can't drive it, sonny, park it". Well, I've been driving for over 45 years and have driven dozens of manuals. The only car that compares for poor shifting is a Pantera, and you can even get one of those shifting better than a C5.
Why in the world could GM not get a better shift out of these cars? I could understand the first year or two C5s having sub-par shifting but you would think that by about 2000 they could have improved it. Sometimes I think I should put a crowbar in my car and use it to lever from gear to gear. Maybe the lug wrench would work. I swapped fluids, which helped a tad, did--and then undid--the detent shim(only made the shift sloppy, 'tho one washer rather than two wasn't too bad). I hear the 2008-2009 C6 manuals have a pretty good shift--has anyone reading this experienced them and can comment? Regards, Ralph Boineau in central South Carolina.

My C5 shifts like the Hawaiian breeze by comparison. Predictable and smooth.

I learned to drive manual driving my 03Z home with an MGW shifter...ive never missed a gear to this day 3yrs later...its firm, crisp, and always finds the right gear. Amsoil atd made it even better.

Unlike the Hurst it replaces the lower assembly as well and unlike the C6 it doesn't need to be cut down to not sit stupidly tall.
However the short throw means that the transmission provides more resistance than necessary. So you need to add 'anti-venom' washers to the transmission (which I'm doing along with a 'skipshift delete dongle' while the car is in the air). Until you do that it will feel like a gated shifter crossed with a tractor, very precise but needing of a firm hand.

The stock box is pretty damn mushy, I got used to it and was able to drive it fine but I don't regret getting the MGW and it was a fun install compared to rusty manifolds, o2 sensors and GM electrical clips... if you don't include taking out the console (that actually kinda sucked mainly due to the damn TCS connecter).

I have to put my .02cents. He didnt understand evert time he went to trans place. The tech new right away what the problem was. IT WAS THE NUT BEHIND THE WHEEL. He just didn't get it. He never figured it out and sold the car.

My 04 Z lot's HP had Callaway shifter would just at the wrong time lock up under hard acceleration read all the fixes got better but still at times but no at just the wrong time locked up let off the gas keep pressure on the shifter then will shift. it's a C-5 thing ..

corvettes, being performance cars, just have transmissions that make audible clunks and rattles with normal operation, and to those used to driving mundane sedans, it can be off putting at first. in order to have the capacity to handle all that torque, they are built beefy, and will not sound or feel like a slippery synchro mazda transmission with a 130lb torque capacity. there are trade offs. In fact, the C5 with torque tube and all is still quieter than the ZF in my 90 C4, which sounds like a rock tumbler while idling in neutral.

Do the antivenom shim mod to the detent bolt on the pass side of the tranny for smoother shifting .. it works --i have MGW with the shim mod and its sweet http://forums.corvetteforum.com/c5-t...need-pics.html
